AF_ALG "Nightmare" Being Further Limited In Linux 7.3 With New Sysctl Knob

The Linux kernel's AF_ALG interface was deprecated in Linux 7.2. This interface for letting user-space programs interact directly with the Linux kernel crypto API has proven to be a "massive attack surface" due to a variety of security concerns. With its deprecation in Linux 7.2, some AF_ALG features are already removed and for Linux 7.3 this interface is being further restrained...

"I'll Make The Linux Kernel Mailing List Burn": Prominent LLVM Linux Developer Returns

One of the original developers behind the work to allow the Linux kernel to be compiled using LLVM/Clang as an alternative to the GCC compiler is now back in the saddle working on LLVM Linux support. LLVM/Clang support for building the Linux kernel has been important for improving code portability and addressing GCC'isms, making use of LLVM compiler features not yet found with the GNU toolchain, evaluating the performance between GCC and Clang, and all the more important these days with the Linux kernel Rust integration...

EHEA 10Gb Ethernet Driver Being Retired By IBM As A Relic Of Outdated POWER Hardware

In 2026 it's not too surprising when seeing old PCMCIA and ISA drivers being removed from the mainline Linux kernel source tree and old very low-speed network interfaces, with arguably the most surprising fast being how long they lasted in the mainline kernel. Meanwhile for the upcoming Linux 7.3 kernel, one of the first 10Gb Ethernet drivers is already set for retirement from the mainline Linux kernel...

Vulkan Video H.264/H.265 Encode Now Working For Intel Alchemist GPUs On Linux

Earlier this year Vulkan Video encode was disabled on newer generations of Intel graphics hardware due to insufficient testing with the Intel ANV open-source driver. That impacted Gen12.5 graphics and newer - basically Alchemist and anything newer. Now at least Gen12.5 graphics with the likes of the Arc A-Series is seeing H.264 and H.265 encoding re-enabled...

OpenSSH 10.4 released

OpenSSH 10.4 has been released. In addition to a number of security and bug fixes, there are a few notable changes; this release adds experimental support for a composite post-quantum signature scheme combining ML-DSA 44 and Ed25519 as described in this IETF draft. With 10.4, if OpenSSH is compiled with sandbox support it will fail on Linux systems that have not enabled SECCOMP or NO_NEW_PRIVS; prior to this release, sshd would log an error but continue operation. See the release notes for a full list of changes.

[$] The kernel's iomap layer

Conversations about the kernel's filesystem implementations often involve a layer called "iomap", but relatively few people can reliably say what iomap actually is. That is just the kind of gap that LWN exists to fill. In short, iomap handles the mapping between data in the filesystem space (identified by a file of interest, and an offset within that file) and in the storage space (which may be a memory location, or a set of blocks on a storage device). Using that mapping, iomap handles a long list of common, filesystem-related tasks, allowing a lot of boilerplate code to be removed from individual filesystem implementations.
